G. This word reminds me of the movie Accepted. The movie is about a kid that can't get into college. Every college that he applied to rejected him. Since he doesn't want his parents to be diappointed, he makes up an acceptance letter. When his parents want to meet the dean of the college he has to be imperious to transform an old, abandoned building into an acceptable college school.
